@graysky Thanks a lot for the repo it is much appreciated. At the the risk of being cheeky though i would like to ask if its possible to get the 'generic' kernel to be built with 1000Hz enabled instead of 300Hz. Feel free to tell me to $%^£^%"!!Again thanks for the work Graysky.

Setting 1000Hz as default is part of the patch, so I guess you could argue both ways in terms of "Vanilla package with ck patches".

How do you recommend I use this?It's designed so that you just patch it in and use it. You shouldn't need todo anything at all. But since people still want to know every last thing...THESE ARE OPTIONAL FOR LOWEST LATENCY. YOU DO NOT NEED THESE!Configure your kernel with 1000Hz, preempt ON and disable dynamic ticks.What about other Hz, no preempt and dynamic ticks?The reason I recommend the above settings is these will have the best possiblelatencies which is by far the most important feature of a scheduler on adesktop.

No idea if it makes any difference, although Kolivas describes 300Hz/preempt on/dynticks on as a "suitable android phone setting".

/OT: sorry for the noise on the AUR package, I should read more carefully... second post somehow happened when I tried to delete the first one.

Re: unofficial linux-ck repo with cpu optimized packages is ONLINE

Thanks again graysky; although #offtopic, I wonder which build I should choose for a Centrino Duo (T2300)... what I've heard ranges between Prescott, Pentium 4, and Core 2

Which seems to point to core 2.... but prescott was recommended by an intel dev or something and i believe this came out before core 2... (as anonymous stated)

edit: ok, this is T2300's output

Re: unofficial linux-ck repo with cpu optimized packages is ONLINE

One question graysky:I was just wondering, I have an Athlon II X4 which is supposed to be a k10 family processor. Is there a specific option for this kind?

Or should i use K8 optimized or the generic one?

The generic one will work for any supported processor. As to your specific chip, the only option supported by the kernel for AMD aside from generic x86_64 is "Opteron/Athlon64/Hammer/K8" which reads as follows, "Select this for an AMD Opteron or Athlon64 Hammer-family processor. Enables use of some extended instructions, and passes appropriate optimization flags to GCC." If you can verify that the Athlon II X4 is one of those, I'd say go for it. If not, I'd use generic x86_64.

I've installed kernel26-ck-atom, but when I try to boot with this kernel - everything is ok until I try to run Xorg. I'm gettin' my Openbox desktop and I can see some tray utilities too, and there's even wallpaper (which means that cairo-compmgr composite manager started) - but system totally freezing. And I see animated mouse cursor in center of screen. Rebooting works only by hard-reset.

Can't you just use kernel26-pf?

I'm sure that is maybe a best option, but really i'm a noob in this of compile kernels. For strange reason i can't use compiled-by-me kernel26-pf (well, it was compiled good but when i try to use the network don't work), i think the function of module_db script in this PKGBUILD is the part that make the magic xD.
